Concurrency Control in Multithreaded Environments with SemaphoreSlim in C#

This article explores concurrency control in multithreaded environments using the SemaphoreSlim class in C#. SemaphoreSlim is a lightweight semaphore implementation that limits the number of threads accessing a resource simultaneously, making it ideal for I/O operations. The article explains its operation, advantages and disadvantages, as well as providing practical implementation examples in scenarios such as database access and external services.
